1 Floating urbanization, the ultimate future proof solution Karina Czapiewska

2 3 major trends A 40% increase of the total build environment Effects of climate change Shortage of land, energy, food and resources

8 Land reclamation Floating urban development Characteristics: - Large investement needed to start - Sealevel rise protection with additional dikes - Destroys local aquatic ecology Characteristics: - Large scale and small scale possible - Adapts to sealevel rise - Water quality and ecology benefits 8

15 INDYMO Monitoring water quality Insight into the aquatic environment. The type of fish and aquatic organisms and biodiversity present, are indicators of the ecological state of water bodies.

16 Creating more value for people and planet People Prosperity Planet Education and knowledge Monitoring of water quality and biodiversity Field research about impacts of floating green and structures on ecology Open-air classrooms Learning by experience (children) Ethics and culture Experience and share of landscape cultural values Human/nature relationships Health and wellness Clean air Relax Outdoor activities Job creation Research, monitoring, green management, tourism, design, construction Value creation Eco-tourism, recreation, education Profit Business Contribution to local economy Innovation Integration of technologies Testing and developing Global impact: create a new Dutch export product Habitat creation and biodiversity New habitat for plants (helophytes), mussels, birds and fish Enhance biodiversity Improve ecosystem services Resource efficiency Energy efficient houses Use of renewable energy sources Combination of systems/functions that can benefit from each other Waste reduction/recycling Reuse of waste and recycle Life-cycle management LCA of materials and buildings Responsibility To species and ecosystems, but also to future generations Aesthetic Emotional response to the beauty of nature

17 Economy in French Polynesia Main contributors: Financial and welfare transfers from metropolitan France (~55% of French Polynesia s GDP) Pearl farming Tourism Sources:

18 Current challenges Economic Economy based on sensitive industries Large import compared to export Demographic Ageing of farming population Wage levels and social welfare considerably higher than other countries in the region Environment Protecting environment from exploitation of resources and invasive species Conserving biodiversity Waste and waste water Climate change Sources:

19 New economic opportunities Eco tourism experience Clean technologies Cosmetology Food and feed industries Synthetic chemistry Sources:

20 French Polynesia as leader innovation ground for marine biotechnology Next to information technology, biotechnology is seen as the next engine of growth by all governments in industrialized countries. The marine environment is an inexhaustible source of innovation for biotechnology specialists. Because of its wide maritime domain and diversity of ecosystems, French Polynesia is an unique and privileged area for research and development of marine biotechnologies. Sources:

21 Contribution of floating development to local economy test clean technologies help the transition to a bio-based economy provide local food support the research aiming at characterising marine species biochemically and pharmacologically allocate some of the profits from bioprospecting to conserving biodiversity Source:
